We look at the division of 30726274 by 421 
Our goal is to divide 30726274 by 421.

Going ahead to step 1:
The number 421 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 421

Step 2:
When dividing 30 by 421, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 421

Moving on to step 3:
307 divided by 421 is 0 with a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 307 and we're left with 307.
Append the next digit (2) from the dividend to 307 and continue with: 3072 / 421

Let's proceed to step 4:
421 can be fit into 3072 7 times, resulting in a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 2947 from 3072 and we're left with 125.
Include the next digit (6) from the dividend after 125, then repeat: 1256 / 421

Let's proceed to step 5:
If we divide 1256 by 421, we get 2 and a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 842 from 1256, we get 414.
Include the next digit (2) from the dividend after 414, then repeat: 4142 / 421

Let's proceed to step 6:
If we divide 4142 by 421, we get 9 and a remainder of 353.
Record the quotient 9 as the next digit in the result. 
Result so far: 729.0
The remainder is 353 after subtracting 3789 from 4142.
Append the next digit (7) from the dividend to 353 and continue with: 3537 / 421

Step 7:
3537 divided by 421 is 8 with a remainder of 169.
Write down 8 as next digit of the result. 
Result so far: 7298.0
If we subtract 3368 from 3537, we get 169.
Fetch the next digit (4) from the dividend, attach it to 169 and continue: 1694 / 421

Advancing to step 8:
The number 421 fits into 1694 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 72984.0
Subtract 1684 from 1694 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
421 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 72984.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
1000 divided by 421 is 2 with a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 72984.02
If we subtract 842 from 1000, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 11:
1580 divided by 421 is 3 with a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 72984.023
Subtracting 1263 from 1580 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 12:
When dividing 3170 by 421, we get 7 with a remainder of 223.
Put 7 as the next digit of the answer. 
Result so far: 72984.0237
The remainder is 223 after subtracting 2947 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 13:
2230 divided by 421 is 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 72984.02375
Subtract 2105 from 2230 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
The number 421 fits into 1250 2 times, leaving a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 72984.023752
If we take 842 away from 1250, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 15:
If we divide 4080 by 421, we get 9 and a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 72984.0237529
The remainder is 291 after subtracting 3789 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 16:
When dividing 2910 by 421, we get 6 with a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 72984.02375296
Subtracting 2526 from 2910 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 72984.02375296, with a leftover of 3.84e-07.
